Bringing home a Great Dane puppy is a commitment to feeding a dog that will eventually stand taller than most kitchen tables. When that gangly frame struggles to keep weight on, it’s stressful for owners who just want their giant to thrive.
Not all dog foods are up to the task. A formula that works for a Labrador won’t necessarily fuel a Dane’s rapid growth and massive adult calorie needs. You need high protein for lean muscle development, joint-supporting nutrients like glucosamine to protect those long legs, and calorie-dense recipes that won’t require a second job to fund.
We’ve surveyed the market’s top contenders across major brands-from budget-friendly bags to premium grain-free recipes-to help you pick the right fuel for your gentle giant. Whether your Dane is a picky eater or an active teenager burning through every calorie, this guide compares the options that matter.

How We Evaluated These Dog Foods for Great Dane to Gain Weight
We didn’t run these through months-long feeding trials across multiple Great Danes. What we did: cross-referenced 7 dog food models from 5 distinct brands across 5 decision axes-protein content, breed-specific formulation, ingredient quality, joint support, and real-world owner feedback. We triangulated published nutritional analyses where available, compared formulation specifics like protein percentages, glucosamine inclusion, and calorie-density proxies, and aggregated owner feedback on palatability and digestive tolerance against those specs.
The scoring framework weighted real-world performance (60%)-how well each food’s formula aligns with the demands of a rapidly growing or underweight Dane-against feature differentiation (40%)-unique advantages like explicit high-protein percentages, large-breed tailoring, or novel ingredient profiles. We have no commercial relationship with any brand; recommendations track fit and differentiation, not brand preference. If your Dane struggles to maintain weight, the Nature’s Recipe Salmon is the top pick; if joint support tops your list, the Lamb formula serves you better.
How to Choose the Right Dog Food for Your Great Dane to Gain Weight
How Much Protein Does a Great Dane Need to Gain Weight?
Protein is the building block of muscle, and for a growing or underweight Dane, it’s non-negotiable. Look for foods with at least 25-30% crude protein on the guaranteed analysis; for actively working or very lean dogs, 32% or higher-like the Purina ONE True Instinct-is ideal. Animal-based proteins (salmon, beef, lamb) are more bioavailable to dogs than plant-based ones, so check that a named meat is the first ingredient.
But protein alone won’t do it. You also need sufficient fat (typically 12-18%) for calorie density. Great Danes have a high metabolic rate relative to their size, so even a slight calorie surplus helps. The Nature’s Recipe Salmon and Lamb recipes both deliver that balance without relying on fillers.
Joint Support: Why Glucosamine and Chondroitin Are Non-Negotiable
Danes are prone to hip and elbow dysplasia, arthritis, and cruciate tears. Any food you choose should include natural sources of glucosamine and chondroitin (often from chicken meal) or be fortified with them. The Nature’s Recipe Lamb recipe and Purina ONE +Plus Large Breed both explicitly support joint health-a reassuring feature when every kilo gained stresses those long limbs.
Omega-3 fatty acids from fish oil also help reduce inflammation. The Blue Buffalo Life Protection Fish & Brown Rice is a standout here, with whitefish as the first ingredient, supplying a direct source of EPA and DHA.
Grain-Free vs. Grain-Inclusive: Which Is Better for Weight Gain?
The grain-free versus grain-inclusive debate matters less for weight gain than calorie profile. Grain-free foods often swap grains for potatoes, peas, or legumes, which can be just as calorie-dense. However, some Danes have genuine grain sensitivities that cause dull coats or itchy skin, so grain-free options like Nature’s Recipe or Beyond Superfood Blend may relieve those symptoms.
On the flip side, whole grains like brown rice and oatmeal provide steady, digestible energy and are generally well-tolerated by large breeds. Dog Chow Complete and Blue Buffalo include grains and still support healthy weight gain. The choice ultimately depends on your dog’s individual tolerance and your vet’s advice.
Comparing Our Top Picks: Nature's Recipe vs. Purina ONE
If you’re torn between the top-ranked Nature’s Recipe Salmon and the high-protein Purina ONE True Instinct, here’s how they differ. Nature’s Recipe is grain-free and relies on single-source meat proteins (salmon or lamb), with a shorter ingredient list that appeals to owners wanting minimalist nutrition. Owners frequently comment on how much their dogs enjoy the flavour, which can be a tipping point for finicky eaters.
Purina ONE True Instinct, on the other hand, packs a higher protein punch (32%) from a beef-and-salmon duo and is marketed for active lifestyles. It includes grain and is fortified with four antioxidant sources. If your Dane is lean and highly active, the extra protein and calories might push the needle. For the average adult Great Dane needing gradual, healthy weight gain, Nature’s Recipe Salmon is the smoother choice.
Budget-Friendly Options That Still Pack on Pounds
Feeding a 60 kg dog can strain the wallet fast. The Dog Chow Complete Chicken is the most affordable option in this lineup and still carries the AAFCO seal of 100% complete and balanced nutrition. While it lacks the specialized ingredients of premium brands, it meets basic protein and fat requirements for weight maintenance-just be prepared to supplement with joint-rich toppers if your Dane needs extra support. For a step up in quality without a massive price jump, Beyond Superfood Blend offers cleaner ingredients at a mid-range cost.
Frequently Asked Questions
What's the difference between Nature's Recipe Salmon and Purina ONE True Instinct for weight gain?
The primary difference is protein source philosophy. Nature’s Recipe Salmon takes a grain-free, single-protein approach, appealing to dogs with sensitivities. It’s well-liked by owners for its palatability and digestive ease. Purina ONE True Instinct, meanwhile, boasts 32% protein from two meat sources (beef and salmon), along with grains for sustained energy. For a Dane that needs aggressive muscle building or has high activity levels, Purina ONE may be more effective; for a sensitive stomach or a preference for minimal ingredients, Nature’s Recipe wins.
Should I choose a large breed formula or a high-protein diet for my underweight Great Dane?
Ideally, both. Large breed formulas like Purina ONE +Plus Large Breed contain the right calcium-phosphorus ratio and natural glucosamine for controlled bone growth and joint health, which is critical during growth phases. However, if your Dane is already severely underweight, a high-protein, calorie-dense formula like Purina ONE True Instinct becomes a priority to add mass. You can also alternate or mix these types under veterinary guidance. The Nature’s Recipe Lamb recipe bridges the gap by offering decent protein with joint-supporting nutrients.
Can I add wet food or toppers to my Great Dane's dry food to increase calories?
Yes, and it’s a common strategy. Adding a high-quality wet food, bone broth, or even a freeze-dried raw patty (like Stella & Chewy’s) can significantly boost palatability and calorie intake without upsetting the stomach. However, be mindful of over-supplementing-stick to a 75/25 dry-to-wet ratio initially. For Danes that turn their noses up at dry food alone, mixing in a salmon oil supplement or a spoonful of plain pumpkin can also entice eating while adding healthy calories.
How quickly should a Great Dane gain weight on a high-protein diet?
Safe weight gain for a Great Dane is gradual-aim for 0.5-1 kg per week, depending on starting condition. Too-rapid gain stresses joints and can exacerbate hip dysplasia. Weigh your dog weekly and adjust portions based on the food’s calorie density (kcal/cup). A high-protein food like Nature’s Recipe Salmon or Purina ONE True Instinct supports lean muscle rather than fat, so you’ll see a firming of the frame before a dramatic number jump. Always consult your vet if progress stalls.
Final Verdict
For most Great Danes that struggle to maintain weight, the Nature’s Recipe Grain Free Salmon, Sweet Potato & Pumpkin hits the sweet spot: high-quality protein, enthusiastic owner feedback on taste, and a grain-free, digestible recipe that keeps energy up and stomachs settled. If your Dane has joint concerns, the lamb version brings built-in glucosamine support. For the need-muscle-now crowd, Purina ONE True Instinct’s 32% protein is a focused performer, while budget-conscious owners can trust Dog Chow Complete to keep the bowl full without emptying the bank account. Whichever you choose, pairing the right food with consistent mealtimes and vet monitoring will help your gentle giant reach and maintain a healthy weight.
